Geo-electromagnetic methods, especially the magnetotelluric (MT) sounding technique, are irreplaceable geophysical methods used for imaging the Earth’s subsurface electrical structure. The ...

Abstract: We present a distributed conjugate gradient method for distributed optimization problems, where each agent computes an optimal solution of the problem locally without any central computation ...

Abstract: A variational formulation of the Cauchy problem for the Laplace equation is studied. An efficient conjugate gradient method based on an optimal-order stopping criterion is presented together ...

The repository consists of several parts. In the krylov folder implementations for the conjugate gradient method and GRMES method are provided. Further, several preconditioner (Jacobi, ILU, IC) are ...
